In this explainer, we will learn how to describe polar and nonpolar solvents. Solubility can be defined as the tendency of one chemical substance to dissolve in a solvent and form a solution. The solute can be a solid, a liquid, or even a gas and the solvent can be made up of almost any type of molecule. Some substances will be soluble in polar ...
13 gru 2023 · Solvents that are very polar will dissolve solutes that are very polar or even ionic. Solvents that are nonpolar will dissolve nonpolar solutes. Thus water, being polar, is a good solvent for ionic compounds and polar solutes like ethanol (C 2 H 5 OH).
19 maj 2021 · What is it that makes a solute soluble in some solvents but not others? The answer is intermolecular interactions. The intermolecular interactions include London dispersion forces, dipole-dipole interactions, and hydrogen bonding (as described in the previous section).
16 kwi 2023 · Example \(\PageIndex{1}\): Polar and Nonpolar Solvents. Would I 2 be more soluble in CCl 4 or H 2 O? Explain your answer. If necessary, manipulate their molecular models below.
Now that we have examined the solubility of substances in polar and nonpolar solvents, let’s make a list of some common solvents that we can choose from. Some common nonpolar solvents include hexane, benzene, and carbon tetrachloride.
For example, the water solubility of oxygen is approximately three times greater than that of helium (there are greater dispersion forces between water and the larger oxygen molecules) but 100 times less than the solubility of chloromethane, CHCl 3 (polar chloromethane molecules experience dipole–dipole attraction to polar water molecules).
Figure 1: The Roman aqueduct in Segovia, Spain. image ©David Corral Gadea. While researchers debate whether Rome’s lead levels were high enough to cause widespread poisoning, one thing is certain: the Romans drinking that water couldn’t see the lead in it.
